AX84 P1 Tube Guitar Amplifier Project
[classic projects]
[current version] [testing version] [old
versions]
Overview
The P1 is a simple tube amp modeled after the classic small
guitar
amps of the 50's and 60's. It's designed to be a managable project for
the first time builder while still offering a satisfying result. An
understanding of the dangers of electricity is required to build this
amp, but it has been successfully built by a number of people with no
previous amp building experience. Although it is a practice amp, you
can certainly mic it and use it in a gig.
Be sure to check out the pictures and sound clips below of various
flavors of this amp as built by real people.
Features
- 12AX7 preamp tube provides two stages of preamp gain.
- EL84/SV83 power tube in Class A, Single Ended configuration
provides a very loud 5 watts or so of output power.
- Bass, Mid and Treble tone controls.
- Single knob gain control increases the amps volume while
increasing
the amount of overdrive. It doesn't get a pristine clean tone or a
raging death metal tone, but occupies that warm territory in between.
Use the amp with a distortion pedal for added flexibility, or use the
volume knob on your guitar to vary the amount of power-tube overdrive.
Skill Level: beginner
--- Status: Ready to Build.
